Apple Studio Freezing Up

In the last several weeks, my Mac Studio has stopped responding after it goes to sleep. I have had to do a hard shutdown (pushing the "on" button for several seconds) and hard start up. On a few occasions, minutes after I shut down the computer using the menus, the computer turned itself back on. A couple of times recently, after I start the computer, the computer stops responding at the black screen just before the desktop should appear. I have had to do a hard shutdown and start over again. Any thoughts on resolving the problem?
